5 QR Code Mistakes That Hurt Your Business (And How to Fix Them)

You use them on business cards, menus, flyers. But if your QR codes aren’t working properly, you’re handing customers a frustrating experience. The good news? Just avoid these 5 mistakes.

1. Using Dynamic QR Codes When Static Ones Suffice

The Problem: Paying monthly fees for "editable" QR codes you never update. Worse, if the service shuts down, your codes stop working.

The Fix: Codex QR generates forever-static QR codes. Perfect for:

• Email addresses or phone numbers
• Links to fixed pages (e.g., your Google Maps location)
• WiFi passwords (works offline!)

2. Poor Contrast or Busy Backgrounds

The Problem: A black QR code on a dark blue background? 30% of smartphones won’t scan it.

The Fix: Codex QR warns you in real-time about low contrast and lets you invert colors with one click.

3. Microscopic Sizing

The Problem: A 1x1 cm QR code on a billboard? It’s like writing a phone number in size 8 font.

The Golden Rule: Each QR module (the tiny squares) should be at least 0.2 inches (0.5 cm). Codex QR lets you choose the exact size for scanning distance.

4. Linking to Non-Mobile-Friendly Pages

The Problem: 95% of scans happen on smartphones. If your link opens a PDF or desktop-only site, you’ve already lost.

The Smart Fix: Codex QR includes a mobile preview to test links before generating the code.

5. Skipping the Call-to-Action

The Problem: A QR code without explanatory text gets 70% fewer scans.

• "Scan to unlock 10% off"
• "Get directions to our store"
